Thanks so much, Shawn!! :)

Dear Alex, I am also very curious about the same thing. Have you already successfully tested the 256GB cards? Would you say that theoretically 512GB or even 1TB cards are also compatible with Audiomoth? If so would these SD cards need to meet specified technical requirements? Thanks so much, Anton

Alex, thank you so so much for help!!

Hi Alex, Thank you so much for swift and helpful response! The only Wav files written were: 19700101_010003.WAV (4.29 GB) 19700101_132541.WAV (1.93 GB) 19700101_132542.WAV (4.29 GB) I used the AudioMoth Filter Playground for the 1.93GB as you suggested and it says: AudioMoth 247475035FDF1F95 Recorded at 13:25:42 01/01/1970 (UTC+1) by AudioMoth 247475035FDF1F95 at low gain while battery was 4.1V and temperature was 25.2C. Recording stopped due to switch position change. I used a SanDisk Ultra 64GB with ExFat. If I set the recording period to 00:00 - 24:00 and use CUSTOM, I assume Audiomoth starts at midnight and not immediately? Would you recommend using a recording time (e.g. 1795s) or would it be OK to disable this function? I was just afraid that Audiomoth might have difficulties with handling a 10-12 GB WAV file Once again, thank you so much! Anton
